Influence of lubricating-cooling technological means on heat exchange in the contact zone when cutting blanks from polymeric composite materials with cut-off diamond circles

The influence of lubricating-cooling technological means on the heat exchange in the contact zone is considered when cutting the workpieces from PCM with cut-off diamond circles. It is proved that the cooling technological medium and the method of its supply affect the thermal tension of the process of cutting polymeric composite materials by cutting diamond circles. The developed mathematical models of the heat exchange problems under consideration have been confirmed. The relationship of the thermal state of the contacting objects with the characteristics of the cooling technological media, the characteristics of their supply to the treatment zone, the real form of the interacting objects and the contact zone is established.
